变结构电力系统短路故障分块计算的新方法

A New Method of Piece-Wise Solution in Faulted Power Systems with Variable Configurations

提出了用分块法仿真计算变结构大型电力系统短路故障的新模型和新算法。该法完全避免了对原网络节点阻抗(或导纳)矩阵的修正计算和各型故障计算中的重复计算。

A new model and its algorithm are presented in this paper to simulate calculating the electric values of short circuit fault in large-scale power systems with variable configurations. The method proposed herein reduces the computer storage requirements compared with the available approaches. And it completely avoids the modification computation of nodal impedance (or admittance) matrices of the original networks and the repeated calculations for each type of faults.
